The arachnoid membrane; the middle one of the three membranes which invest the brain and spinal cord, separated from the pia mater by the subarachnoid space containing serous fluid. It is usually described as consisting of a parietal and a visceral layer, inclosing the a. space or cavity; Kolliker, however, denies the existence of a parietal layer distinct from the epithelium of the dura mater. Tuke maintains that there is no separate membrane answering to this description, and thinks the name should be dropped. The term has also been applied to several delicate investing and lining membranes. [Lat., Gr.]
